Are you looking for universal upgrade pinion gear for your RC car? A: We can help, we provide 5mm hole 32P pinion gear set comes with a set screw, they work well and have a secure fit with no modification needs. Package include: 1 X 32P 5mm 17T pinion gear 1 X 32P 5mm 18T pinion gear 1 X 32P 5mm 19T pinion gear 1 X 32P 5mm 20T pinion gear 1 X 32P 5mm 21T pinion gear 5 X 32P Screws 1 X Note: 💡【32P】is the pitch of each tooth on the pinion gear and the 17T 18T 19T 20T 21T is the number of teeth on the pinion gear. You have to make sure your spur gear and pinion gear have the same pitch, or the teeth won't mesh. 💡【5mm】The pinion gear shaft diameter or bore is 5mm, make sure your RC motor shaft have the same diameter. 💡Make sure you thread lock the grub screw. They are hard to find when they fall out. 💡Larger gears will result in higher speeds while smaller gears provide more torque. For quicker acceleration go for a smaller pinion gear (with fewer teeth) and a larger spur gear (with more teeth). Your car will accelerate off the mark very quickly with more torque, and you'll also benefit from cooler running temperatures, extending the life of your motor and ESC. 💡💡 How to install the pinion gear: You will probably need to loosen the motor a bit, in order to fit the pinion gear on. Make sure you lock it in place on the flat portion of the motor shaft. When you are tightening it back up, make sure you leave about a gap between the pinion gear and the spur gear. That gap will be very small. It should be about the width of a piece of paper. ## Features - 【Durable】Durable metal construction for long-lasting performance. - 【More Funny】Provide the option of being able to change your gear ratio for different track conditions. - 【💡】32P is the pitch of each tooth on the pinion gear and the 17T 18T 19T 20T 21T is the number of teeth on the pinion gear.
